hermanradtkeon To write non-fiction, draw the trunk, then the rest of the tree

As I understand it, the author was sharing the story to convince the audience he was a good writer and, thus, we should value his opinions on how to write non-fiction.

hermanradtkeon Bonsai: Janestreet's UI Library

Are there any other?

Namespaces are heavily discouraged. Some teams still use enigma but most people in the know us unions of strings.

I know the TS team regrets enums and I have not seen any plans for adding additional keywords that break type stripping.

hermanradtkeon WolfIP: Lightweight TCP/IP stack with no dynamic memory allocations

hermanradtkeon `satisfies` is my favorite TypeScript keyword (2024)

> we end up with a mix of both Zod and types and sometimes types that need to be converted to Zod

In my code, everything is a Zod schema and we infer interfaces or types from the schemas. Is there a place where this breaks down?

hermanradtkeon Event Sourcing in Go: From Zero to Production

> it expects a level of correct-design-up-front which isn't realistic for most teams

It requires a business that is willing to pay the maintenance cost of event sourcing in order to get capabilities needed capabilities (like an audit trail or replayability).

hermanradtkeon OpenTelemetry Is Great, but Who the Hell Is Going to Pay for It?

New Relic, Datadog, etc are selling their original offering but now with otel marketing.

I encourage the author to read the honeycomb blog and try to grok what makes otel different. If I had to sum it up in two points:

- wide rows with high cardinality

- sampling

hermanradtkeon My AI skeptic friends are all nuts

Many do. In their GitHub repos right next to the code.

hermanradtkeon Migrating to Postgres

In what cases is your join causing a table lock?

hermanradtkeon Compiler Reminders

That is a feature. Compose instead of extending.

hermanradtkeon The hidden cost of AI coding

Yes, there are bad places to work. There are also places that require detailed time tracking, do not allow any time to write tests, have very long hours, tons of on-call alerts, etc.

hermanradtkeon Things Zig comptime won't do

I wish for “strict” mode as well. My current thinking:

TypeScript is to JavaScript

Zig is to C

I am a huge TS fan.

hermanradtkeon Achieveing lower latencies with S3 object storage

I thought S3 was first as well.

hermanradtkeon Google Being Forced to Sell Chrome Is Not Good for the Web

Costco prices are very low. They intentionally make very little margin on what people buy.

Their margin comes from subscriptions.

hermanradtkeon Zlib-rs is faster than C

> basically written in C

Unsafe Rust still has to conform to many of Rust’s rules. It is meaningfully different than C.

hermanradtkeon Google Being Forced to Sell Chrome Is Not Good for the Web

> That's like saying that resteraunts are just credit card swiping businesses.

You are being sarcastic here, but ironically you are not far from the truth. The core financial model of a businesses is not always obvious.

McDonald’s is a real-estate business. Costco is a subscription business.

hermanradtkeon React has become the 'Linux kernel' of modern software development

> Some react devs literally don't even know that HTML can be rendered server side.

Sadly, many do. Only later do they realize it is orders of magnitude slower than rendering a template and more cpu intensive. Combine that with the fact that node.js prefers to have an IO heavy workload, but instead we get a cpu heavy one.

React is fine, but SSR has a long way to go before it is “good”.

hermanradtkeon PR process killing morale and productivity

My bias is towards merging. Trivial issues can be fixed in a future commit or PR.

hermanradtkeon Hey, wait – is employee performance Gaussian distributed?

> On the other hand, one of the better dynasties of the past decade was accomplished by the Golden State Warriors in the US NBA thanks to underpaying one of the all-time great players in NBA history because he suffered a series of ankle injuries early in his career and scared off other suitors.

hermanradtkeon Steve Ballmer was an underrated CEO

I cannot edit anymore, but this is the talk descrption: https://www.thestrangeloop.com/2016/reproducibility.html

hermanradtkeon Steve Ballmer was an underrated CEO

Thank you for the link but I was looking for the reproducibility talk.

hermanradtkeon Steve Ballmer was an underrated CEO

> Much like Gary Bernhardt's talk, which was panned because he made the problem statement and solution so obvious that people didn't realize they'd learned something non-trivial

I really want to see this video, but I cannot find it anywhere. I checked https://www.youtube.com/playlist?list=PLcGKfGEEONaDvuLDFFKRf... but I believe Gary asks that his videos not be shown (which I am fine with). I also checked https://www.destroyallsoftware.com/talks but I do not see it there either.

Should I be looking somewhere else?

hermanradtkeon Ask HN: What type of Auth are you using on your side projects?

They can, and do, introduce breaking changes in major releases. That is the issue.

hermanradtkeon Rust needs a web framework

Rails clones in modern languages don’t get wide adoption. I wrote about why I think that is: https://hermanradtke.com/why-your-rails-like-framework-is-no...

hermanradtkeon Ask HN: What type of Auth are you using on your side projects?

Keycloak has too many new major releases. It is a real pain to keep up with.
